ABP Contract Scaffolding

Generate Application.Contracts layer code to enable parallel development workflows.

Purpose

Contract scaffolding separates interface design from implementation, enabling:

• abp-developer to implement against defined interfaces
• qa-engineer to write tests against interfaces (before implementation exists)
• True parallel execution in /add-feature workflow

When to Use

• Backend-architect creating technical design with contract generation
• Preparing for parallel implementation and testing
• Defining API contracts before implementation starts
• Interface-first development approach
